cocos2d-x接受键盘事件，左右键, 多点触摸

首先在AppDelegate.cpp加入以下代码，一定要在AppDelegate::applicationDidFinishLaunching()上，声明用的。

copy

boolAppDelegate::applicationDidFinishLaunching(){
1. //initializedirector
2. CCDirector*pDirector=CCDirector::sharedDirector();
3. CCEGLView*pEGLView=CCEGLView::sharedOpenGLView();
4. #if(CC_TARGET_PLATFORM==CC_PLATFORM_WIN32)
5. //2012.11.07加入键盘处理代码
6. pEGLView->setAccelerometerKeyHook(Win32KeyHook);///////////////////////////////////
7. #endif//CC_PLATFORM_WIN32
8. pDirector->setOpenGLView(pEGLView);
9. //turnondisplayFPS
10. pDirector->setDisplayStats(true);
11. //setFPS.thedefaultvalueis1.0/60ifyoudon'tcallthis
12. >setAnimationInterval(1.0/60);
13. //createascene.it'sanautoreleaSEObject
14. CCScene*pScene=HelloWorld::scene();
15. //run
16. >runWithScene(pScene);
17. returntrue;
18. }

copy

CCScene*HelloWorld::scene()
1. //'scene'isanautoreleaSEObject
2. CCScene*scene=CCScene::create();
3. //'layer'isanautoreleaSEObject
4. HelloWorld*layer=HelloWorld::create();
5. //addlayerasachildtoscene
6. scene->addChild(layer);
7. externvoidWin32SetKeyLayer(HelloWorld*layer);
8. Win32SetKeyLayer(layer);
9. //returnthescene
10. returnscene;
11. }

voidHelloWorld::onWin32KeyEvent(UINTmessage,LPARAMlParam)
1. CCLog("onWin32KeyEventmessage%dwParam%dlParam%d",lParam);
2. /*

24. if(message==256)

36. elseif(message==257)
37. copy
    voidHelloWorld::moveHero(intdiraction)
    1. CCLog("moveHero:%d",diraction);

    2. //现在你就可以上下左右键，看输出的值。
